Abstract

LA PRESENTE INVENTION CONCERNE LES TAMIS UTILISES POUR SEPARER LES PARTICULES SOLIDES DES SUSPENSIONS. LE TAMIS SELON LA PRESENTE INVENTION RENFERME DES BARRES TRANSVERSALES 9 ESPACEES ENTRE ELLES DE MANIERE A ENGENDRER DES FENTES 11, CES BARRES DE TAMISAGE AYANT UNE SECTION TRIANGULAIRE ET TROIS FACES LATERALES DONT L'UNE 10 SERT DE SURFACE DE TAMISAGE, L'ANGLE D'INCLINAISON B DES SURFACES DE TAMISAGE ETANT INFERIEUR A L'ANGLE D'INCLINAISON A DE TAMISAGE, ENGENDRANT AINSI UNE SURFACE DE TAMISAGE EN FORME D'ESCALIER, CE DISPOSITIF PERMETTANT D'ATTEINDRE UNE HAUTE EFFICACITE DE SEPARATION SANS POUR AUTANT REDUIRE LE DEBIT A TRAITER.THE PRESENT INVENTION CONCERNS THE SIEVES USED TO SEPARATE THE SOLID PARTICLES FROM THE SUSPENSIONS. THE SIEVE ACCORDING TO THE PRESENT INVENTION CONTAINS CROSS BARS 9 SPACED BETWEEN THEM SO AS TO CREATE SLOTS 11, THESE SIEVING BARS HAVING A TRIANGULAR SECTION AND THREE SIDE FACES OF WHICH ONE 10 SERVES AS A SCREENING SURFACE, THE ANGLE OF ' INCLINATION B OF THE SIEVING SURFACES BEING LOWER THAN THE SIEVING ANGLE OF TILT A, THUS GENERATING A SCREENING SURFACE IN THE SHAPE OF A STAIRCASE, THIS DEVICE ALLOWING TO ACHIEVE A HIGH SEPARATION EFFICIENCY WITHOUT AS MUCH REDUCING IT .
